Abstract (en)
[origin: EP2963482A1] A spectacle lens design system comprising: a first photographing apparatus disposed to have a first distance with respect to a subject so as to photograph the subject; a second photographing apparatus disposed to have a second distance with respect to the subject so as to photograph a visual target, the second distance being farther than the first distance; a determination means that determines a position of an eye of the subject based on an image photographed by the first photographing apparatus; a visual target decision means that tentatively calculates a position of the visual target based on an image photographed by the second photographing apparatus, and decides the position of the tentatively calculated visual target based on a relative positional and pose relationship between the first photographing apparatus and the second photographing apparatus; a visual line information calculation means that calculates visual line information defined when the subject watches the visual target, based on the determined position of the eye and the decided position of the visual target; a shape design means that designs a shape of a spectacle lens based on predetermined prescription information and the calculated visual line information; and a pseudo moving means that detects, at predetermined time intervals, a position and a pose of a head of the subject based on the image photographed by the first photographing apparatus, and moves, at predetermined time intervals, the decided position of the visual target, in a pseudo manner, by an amount corresponding to a difference of the position of the head before and after detection and a difference of the pose of the head before and after the detection so that the position and the pose of the head of the subject is maintained, in a pseudo manner, before and after the detection, wherein the visual line information calculation means calculates the visual line information based on the determined position of the eye and the position of the visual target moved in a pseudo manner.
